SNOW-CLEANING APPARATUS. I

' Application filed February To all whom it may. concern:

Be it known that I, ARTHUR S. OLSON, a citizen of the United States,residing at Murdock, in the county of Swift and State of Minnesota,haveinvented certain new and useful Improvements in a Snow-OleaningApparatus, of which the followlng 1sa specification.

The present invention relates to a machine for cleaning snow fromstreets, roadways, and the like, and aims to provide a structure whichis capable. ofbeing incoron a truck chassis so that the truck may bedriven along the street, roadway or thelike, and the snow picked up fromin front of the truck and, conveyed to the side thereof.

. designed.

2 Another important object of the invention is to provide a pair ofcollecting conveyors which maybe adjusted to the desired height andwhich may be lifted to an inoperative position.

.Another important object of the inven tion is to provide in'combinationwith the collecting conveyors a pair of beaters for breaking up the snowas it is being picked up by the conveyors, and further the pro .visionof means whereby these boaters may be adjusted in relation to theconveyors A still further important object of the invention is toprovide an apparatus of this nature which is, comparatively simple andefficient structure which may be readily as sembled upon a conventionaltype of truck, one which is readily assembled or disassembled, strong,durable, not liable to readily get out of order, and otherwise welladapted for the purpose for which it is ;With the aboveandnumerous'otherobjects in view as will'appearas the description proceeds, the inventionresidesin certain novel features of construction, and in the combinationand arrangement of parts aswill be hereinafter more fully described andclaimed. r

In the drawings I Figure 1 is a top plan view of the apparatus embodyingthe features of my invention,

Figure2 is a side elevation thereof, Figure 3 is a transverse sectiontaken vertically therethrough and looking rearwardly,

Figu taken substantially on the line of Fig- "conveyors A by means ofbolts 20 orin re 4 is an enlarged detail section v p 5 mounted asuitable source of power, which I 11, 1925. Serial m. 8,474.

ure 2 looking in the direction of the arrow, and i Figure 5 is anenlarged detail view of the crank and ratchet mechanism assoclatedtherewith for lifting the beaters.

Referring to the drawing in detail it will beseen that I haveillustrated a conventional form of automobile truck, but of course, anyother wheeled vehicle could be substituted therefor. In the vehiclewhich I have illustrated, the numeral 5 designates the chassis thereofon which is mounted up rights 6 by means of cross bars 7, said uprights6 being of an inverted V -shaped formation in' the present instance. Theapexes or upper ends of these uprights 6 form journals for receivingpins 8 for pivotally supporting brackets 9 which in turn supportcollecting conveyors indicated generally by the letter A. As is shown toadvantage in Figure 1 there isfla' pair of these collecting conveyors Awhich converge toward'their front ends into scoops 11. Each conveyor Aincludes a pair of spaced vertically extending side walls 12 having theendless conveyor 13 operable therebetween. The

body of this endless'conveyorj 13 has extending transversely thereofcleats 14. Chains '15 are engaged with the edges of the body and withthe ends of the cleats and are trainedover sprockets 16 on the endshafts 17 as is shownto advantage in Figure 2.

An inverted U-shaped' frame 19 has its ends fixed to the inner sidewallsof the any other'suitable manner. A pair of bars 21 and 22 rise from theintermediate portion of the frame 19 and the bar. 22 is a rack barhaving its teeth 23 on the inner edge thereof. A standard 24 rises fromthe forward end of the chassis 5 and a shaft 25 is journaled in theupper end thereof and in a suitable bracket 26 at the dash board of thetruck. A crank 27 is provided on the 7 end of the shaft 25' at the dashboard and a ratchet mechanism 28 is associated therewith as is shown toadvantage in Figure 5. A pinion 29 rotates with the shaft 25 and mesheswith the teeth'23 of the rack bar 22 so that by turning the crank 27 theforward ends of the conveyors A and the scoops 11 may be raised anddesired. I

At the rear of the chassis 5 there is lowered as I have shown in thepresent instance merely by way of example as an electric motor--30. Achain 31 is driven by this prime mover 30 and operates a shaft 32 whichextends longitudinally of the rear portion of the chassis beingjournaled under the conveyor B which will be described later. A beveledgear 33 meshes with a beveled gear 34 on the transversely extend ingshaft 35 which is journaled in standards 36. Shafts 37 are connected tothis shaft 35 by suitable universal joints 38 and is provided withsprockets 39 for drivlng the chains 15 of conveyors A. These shafts 37are journaled in brackets 40 on the bottom of the conveyors A. Then themotor 30 is in operation it will be seen that the chains 15 and cleats14 will travel upwardly over the bottom 13 of each conveyor A fordelivering snow collected on the scoops 11 to the upper ends of theconveyorsj for dumping said snow onto the conveyor B A frame 44 risesfrom the forward end of each conveyor A and the sides thereof areslotted as at 45. A shaft 46 is slidable through theseslots and carriesa beater 47 which includes a plurality of radiating blades'a's isevident from an inspection of Figure 2. Cables 48 are connected tojournal blocks 49 at the outer ends of the shafts 46 and are trainedover pulleys 50- at the upperends of the frames 44. These cables 48 areconnected to a common} cable 51 which is attached to a winding drum 52having an' operating crank 53. By operation of this crank 53 to wind thecable 51 on the drum 52 it will be seen that the beaters 47 may beraised and lowered in respect to the conveyors A. The inner ends of theshafts 46 are provided with sprockets over which are trained chains 55which extend rearwardly and are trained over sprockets carried by shafts56 having universal joints 57 and 58 therein and driven by shaft 59. Abevel gear 60 is mounted on the shaft 59 and meshes with a beveled gear61 on shaft 62 journaled in standards 63 and driven by chains 64 fromthe prime mover 30. A clutch mechanism 65 is incorporated in the shaft62 and is operable from adjacent the drivers seat by member 66 or in anyother suitable manner. It will thus be seen that the conveyorsA may beoperated independently of the heaters 47 as may be desirable, especiallywhen the snow is rather light and there is no necessity of breaking itup.

The conveyor B extends transversely of the chassis and is mounted on thestandards 70 so as to be located below the delivery or upper ends of theconveyors A. This con- .veyor B includes the side walls 71 and 72, thelatter being slanted rearwardly and the bottom 73 over which travel thecleats 74 carried by chains 75 trained over sprockets in the end shafts76 journaled in brackets snow will be collected on the scrapers 11,

broken up by the heaters 47 and delivered by the conveyors A to theconveyor This conveyor 13 will pile the snow collected to the right ofthe vehicle. It will further be apparent that the conveyors A may belifted to I an out-'of-the-way position when desired and may be alsoadjusted in relation to the ground as may be desired by operation of thecrank 27; Further, it is to be noted that the heaters 47 may be adjustedin relation to the conveyors A as will be desired depending upon thedepth of the snow and when these heaters. are not necessary they may belifted tothe upper ends of the slots 45 and the clutch 65 opened so thatthe conveyors will no longer operate. It is thought that theconstruction and operation of the invention will now be clearlyunderstood without a more detailed description thereof, but it isdesired to point out numerous changes in the details of construction,and in the combination and arrangement of parts may be resorted towithout departing from th spirit or scope of the invention ashereinafter claimed and with out sacrificing any of its advantages.

Having thus described the invention, what I claim as new is 1. Incombination, a vehicle, a conveyor mechanism r'ockably mounted on thevehicle to extend longitudinally thereof, frame attached to the forwardend of the conveyor mechanism, a rack bar attached to the frame, a shaftjournaled longitudinally of the vehicle, means for operating the shaft,a pinion on the shaft meshing with the rack bar for raising the forwardend of the conveyor mechanism.

2. In combination, a vehicle, a. conveyor mechanism rockably mounted onthe vehicle, means for adjusting the conveyor 'mecha nism in relation tothe vehicle, a frame including slotted uprights mounted on the forwardend of the conveyor mechanism, shafts the forward end of the vehicle anddelivering it to an intermediate portion" of the vehicle, said conveyormechanisms being rockahly mounted adjacent their rear ends on thevehicle, a third conveyor mounted transversely of the vehicleimmediately below the delivery ends of the first mentioned conveyormechanisms for delivering the snow to one side of the vehicle means foroperating the conveyor mechanisms, a frame attached to the forward'endsof the longitudinally extending and rockahly mounted conveyormechanisms, a rack bar fixed to the frame, a

the rack bar, means for rotating the shaft whereby the forward ends .ofthe rockahly mounted conveyors may he raised or low-- ered, slotteduprights on the forward ends of the conveyors, heaters having shaftsslidahle and rotatable in said slotted uprights, means for rotating theheaters, and means for raising and lowering the heaters.

In testimony whereof I aflix my signature.

ARTHUR s. OLSON.
